To all whom it may coma/21 Be it known that l, lilaniox L. lon'rnn, citizen of the United States, residing at Sit veil TEIlin the county ct *ian Juan and State ol Crier-ado, have invented certain new and useful lniproven'ients in re-Concent 'ators, of which the following is a s 'iecification, reference being had to the accompanying' drawings.

' This invention relates to machines for recovering ininerals which are too fine to be precipitated and separated from foreignnnn terial by passing the same through the ordinary appliances now in use in quartz mills,

and has for its primary object to produce "arranged above the tank or hopper at each side thereof thron 'h which the water may i 2-; pass into collecting chambers to which waste pipes are connected, the screens of each series being independently movalile.

ll ith the ahovc nnd other objects in view as will. become apparcntas the description proceeds, the invention consists in certain constructions, conihirnit-ions and arrangements of the parts that I. shall hereinafter fully describe and claim.

For a full understanding oi the invention, reference is to he htid to the following description and accompanying drawings, in which--- I l ipgure l is aside elevation partly broken away oi? a. machine embodying the present invention; Fig. 2 top plan view thereof; l 3 is a section taken on the line 33 of Fig. 1; Fig. =1 is an enlarged detail section through the bottom wall oi? the tank or hopper showing the construction of the gates; Fig. 5 is an enlarged detail section illusg of the 'ing screens;

ation ported at intervals by the spaced standards in showing 1 connected to a cr uprights ('5, the corresponding standards on opposite sides of the hopper being con nected by t'ansverse liars '7 to which the lower edges of the side walls 5 are secured. ()hliquely inclined truss rods 8 connect these standards (3 and the cross bars 7, said rods being arranged cxteriorly of the tank or hopper and adjacent the side walls 5 thereof. At the upper ends of the side walls 5, the vertical walls 9 are arranged to form an extension of the hopper. To the side walls 9, the lower edges'of the outwardly inclined walls 10 are secured, and these walls form longitudinally extending chamhers 11.

In the longil ndinal walls 9 oi the machine, a plurality of series of filtering screens indicated at. 12 are arranged. Three filtering plates or screens are preferably employed in each series though it will he understood that a greater number may he used, if desired. 'll'lesc screens are mounted for vertical sliding; movement. in the guides 13 and may he independcnily removed when it becomes necessary to clean or repair the same. The innermost filtering; screen 12 at its upper portion is formed '01" impcrlorate material while the lower portion thereof provided with estremely line perforations. The internngdiate screen 12 has slightly larger per- 'tcraiions, while the outermos-st perforated screen is comparatively coarse. These filtering members may be constructed of woven wire or may he in the form of perforated plates.

l l designates the feed line pipe which supplies the mineral inipreginited slime to the tanker hopper of the machine, said pipe being provided with spaced outlet or discharge pipes 15 arranged at opposite sides of the center of the machine. The inclincd side walls of the tank are of course, connected at their ends by the end walls 16 and to one of these end walls, a. series of out.- let pipes 17 are connected. each 01 said pipes ha ving a valve 18. 'llhesc outlet pipes are common deli.

Tilt) harg'c pipe 19.

v the tank orhopper and between these plates and the hopper walls, the pipe coils 222 are arranged. These coils at one of their ends are connected to a common steam Supply pipe 2-1 which extends beneath the hottmu of the tank or hopper, the other end of said coils returning to the source of steam supply or to the coils of a second machine. when the same are employed in series. in the bottom of the tank or hopper, between the side walls 5 thereof, the gates "indicated at are arranged. Any desired number of these gates may be employed, the same being I disposed heneath'the o 'ienings 26 in the hot-v tornof the hopper, and they each includepla'teor disk 27 having apertured ears 28 through which the bolts 29 extend. liuts F30 and are thra'uled upon the respectiveholts 29, the nut serving to ac ")l the grate plate in its closed position. This. plate is provided with a suitable l'nuidhold' 31. in order toopenthe gate to permitkrf the escape ot theponrentrutcs from the inachine, the nut 30 is removed and thenut 3i loosened whereby the gate may be readily swung to ts. open position. longitudirely clan 1p nallyextending conveyer 3i2' oi. any suit? able cons notion is centrally arranged heneath the tanker hopper and receives the coiu'entrates therefrom. I 1

it is a Well known fact that after all of the heavier particles have been precipitated by the use of various concentrating devices, the slime still contains considerable finely coinniinutcd mineral which is so light that it' cannot beprecipit-ated and collected by the ordinary appliances now in. common use. This tine li ht material will readily float in W853 and is carried in suspension thereby. Heretofore, these extremely fine mineral particles have been lost and it is the purpose of the present, invention to recover the very lightest and finest mineral particles which are frequently almost invisible. To this end, the mineral impregnated slime isfed to the tank or hopper until the level thereof rises above the inclined hopper Walls and bet ween the 'alls'fl arranged above the same. As-the only outlets froin the tank are through the filtering: members 12, the finely coihminuted mineral collects upon the inner surface at the innermo t filtering" member, those extreniclv tine particles which are invisible (rollectil'ig'upon the imperfe- ,rate un'ier nor-tine of said filler-in" zLeniher.

are being dried and emptied from ih-e ti.-

serics of outlets 17, operations n amaze from b opening the seve 'al alves 18. The

height of the water in the tank is slowl -lowered by providing! the plurality of outlets 1?, thus giving the fine n'iinezal particles time to attlle upon ill-e collecting; plates 22. filter the water has heen withdrawn from the tank. utezun is turned into the pipe cells 2%. 'lheae steani coils highly heat theplates 22 thus drying the concentrates These dried mineral particles gravitate upon the inclined plates 22 into thetrough at the base thereof: and are collected by opening the several gates thereby perniitting the same to tall upon the conveyor 32" which conveys the same to suitable storagelnns.

' My improved (:(nicentrating machine above described is adapted to he. used in =S8l'lPS, tlu-nu'nneral nnpregnatml slime being fed townie machine to permit the mineral to 4 collect therein while the mineral partirlrs of the other nnichinc. .liy providing;- the greatlyexpedited as a partially iiilt may be "unloade and the partia (rated 5 ie withdrawn therefrom and co: veyei'l though. the pipe 19 to the tank 0:, the adjacent. machine.

in Fig. (3' of the. (lrawingvs. i have a slightly incalilied eonslriiction oi the iii ters which are flirt-ringed upon the tank walls andan automatically actuated valve for releasing the mineral impregnated Wally ter 'and shine so that the same will pass from the tank through the filters. In this downwardly rater/n. a

modified construction, I provide a hood or dcflccting plate 33 which is secured at one I of its edges to the inner face-of the side wall of the tank and extends laterally there w from, the. inner portion of said deflecting plate being downwardly extended at r" angles to the remaining" portion the: This plate providee a hood or housing a pipe 34- which extends through the side wail ot the tank and prevents the mineral deposits irom accumulating in the-vertically disposed entrance nipple 35 of said pipe. This nipple is provided with a saitanie valve seat for engagement by the valve meinher 36 which is seemed to the lower end of a vertically movable rod mounted in suitable guide lirachei's- 38 arranged upon the i tanh Will. 39 in dicates a float provided: with a tubular stein ll} coupled to the outer end of the lrl and a pipe 50 connected to said ipe extent ls to the storage tank or .YU r. A. T-coupling connects the pipes and and to the same, a nipple 51 is no uieeled in which. the plunger 52 is movl-O which niovaljile in one oi. the brackets the upper end of the rod 37 being adusiahly secured in said stein by means of, the set screw ll. in the pipe ill; a valve 42 arranged said valve being opened and closed by means of the rod 43 which mica-ids iujuvardly above the upper edge of 'lhe filter oox or chamber 4-1 is w uni ell upon the outer face of the tank wall and is provided upon one side with a wad oi reticulated material as indicated at which provides a suitable filtering medium. To the lower end of the filtering hos: ill. a pipe at; leading to a storage tank or re voir is connected, said pipe being providrd with a valve at? through which the mineral which may be collected in the tilter box is Withdrawn and returned to the main tank to be again treated.

"the operation of the above described form of the lilter will be readily understood. is the mineral imprcgated slime and water is ted to thetank oi the concentrator, it rises above the hood or deflector plate 33. and elevates the float 3 thereby lifting the rod 37 and moving the valve 3 3 from its i zeat in the upper end of the pipe nipple The Water in the tank Willthus drain 0ft tlll'i'sllgll the pipe into the filtering box 4i a 5 me through the. filtering Wall e5 thereor while the concentrates Wl'llCll may be con.- taine il therein will be caught and re-.ained in. ti be): until drawn oil from the rape iii.

. Fig. 7, l have shown an alarm device which 1 have designed for use in connection willthe filter tank. This device embodies n construction, a pipe 48 the inner open i of which is normally closed by a valve similar to the valve 36 above referred to and operated. by a float 39. Thisfioat, 'er, disposed above the normal level that 39, so that the water will not Eho so me when the valve 36 is opened. valve 336" will remain closed and ll be no outlet of the fluid from the ough the pipe 48.

From this construction, it will be apparent that it anything interferes with the proper operation of the tloat 3!) so that the valve 36 is not moved from its seat to open the en trance to the pipe 34-, and the water and slime in the tank is in imminent danger of overflowing, the continued rise thereof will elevate the float 3 thereby unseating the valve 36 and permitting the Water in the. tank to drain oil through the pipe 48. The pressure of this water upon the plunger 51. will force the rod downwardly, thereby oscillating the lever 56 and engaging the contact plate 57 with the stationary contact Thus the electric circuit is closed and the bell. or other alarm device actuated, to Warn the operator who promptly shuts oil"; further supply of the Water and slime to the oncentrating tank. I

From the foregoing, it is believed that the coi'istruetion and manner of operation of my improved ore concentrator will be clearly Hid fully understood. It will be obvious that by employing the series of filtering members 12, even the very finest mineral particles may be saved. it. will of course he understood that. the principle of the inven tion may be successfully carried out Without necessarily adl'ierin z to the specific construction of the machine as disclosed in the accompanying drawing, as such' construction is susceptible of considerable modification in the foru'i, proportion and arrangement of the several elements eniployed, Without departing from the essential features or acrificing any of the advantages of the invention.
